Be it known that I, NmroN W. H. BROWN, a citizen of the United States,residing at Trenton, in the county of Mercer and 'State l of New Jersey,have invented certain new and useful ImprovementsA in Box-Maga-A Yzinesfor Firearms; and I do hereby'declare the following to'be a full,clear, and exact description of the invention, such as will '10 enableothers skilled in the art to which' it appertains to make and use thesame.

g My invention relates to magazines of the box Atype especially adaptedfor ire arms,I

and has for its object to provide a magazine may be loaded with" greatrapidity, (and which will possess other advantages to be' A d and areadapted torest; when the follower described below. n With these andotherv I construction and' combinations off vparte more fully`hereinafter disclosedlanud -par; ticu'iarly pointed out in theeelaims.

Slidingly tting the said casing 4 is the innercasingv13Y provided at each end with the slots 14 through Vwhich thestems^7 pass. Fitting within said innercasing -13 but not carriedthereby, is the cartridge follower 15 controlled by the the bottom I7 ofsaid inner casing. The

said follower 15 has downwardly extending lends or lugs 18 havingopenings 19 into which' lit the Tshaped. lugs 20', as best shown-inFigs. 1, 5 and 6..A The heads21 of these .lugs slide in said slots 14,as shown,

The innercasing 13, as best shown in Fig. 3,; is further' provided with 'slots28,'4 one on each side to llmit the movement of the stems 27 therein,when the block 23 is moved.'v e outer casing`4 isfurther provided on chside with 'afbayonetslot 30 havingl openings 31 adaptedtc'yrbef-enteredy by the-said stem vportions 27 of thethumb-screws26,and on magazine whereupon the said inner casing 100 ends of the stems 7,as illustrated ilrlig.A 1: 70-

The top portion 35 of the innercasingis beveled oif as shown in Fig. 1,in order that the cartridges'may not catch thereon when the ,innercasing' is being pushed home.

'.Theoperation of my improved box magazine is as follows z-The outercasing 4 is normally fixed tothe fire arm by the ythumb catch y11, andistherefore not intended to be detached frm the arm except at rare in,-tervals when it is necessary to clean the magazine. The follower 15lifts the cartridge is fired, the heads 21 carried' by :said

occupyl a'position about even with the bottoniof the opening33 in theouter casing`4, and cartridges may be inserted one at a time through`thesaid opening 33 until a column ofcartridges occupies the said outercasing 4f When the magazine has been thus lled the bottom casingnlyffmay now be forced pasti-he column of cartridges in the outer screws willcontactl with 'the cam surfaces' 32 whereupon the slide block 23 willbeautoy matically forced .against the .tension of vthe Asgring 25 towardthe leftv. yas seen in 'Fig/"1.

thegslot 30 and the inner casing 13 to be sewhereupon the heads 21 ofthefollower will .Contact with the stems 7 of the set screws 6,

fromfvthe top of the magazine by the bolt 2' As the car s ring 16 forcesthe follower upwardly, and.l

the inner casing and thereby steady the saidv follower and cartridges.Also, the shoulders the lugs or bosses 5 so as to prevent the said thumbscrews from working loose. Further, when the inner casing 13 is loweredinto the position shown in 'F ig. 3, the upper ends of its slot takeagainst they heads 21and the said heads rest upon thesaid stems 7, andtherefore the said thumb screws 6 prevent vthe inner casing from beingwithdrawn and possibly lost.

., The floor 17 of the inner casing is conveniently held in place as bypins 40, and

need not be removed exceptupon very rare n occasions.'

The thumb screws 26 may be setup tightly whileA permitting theinner'casing to move freely at all times. Further, the walls of theinner box 13 extend a distance over the slide block 23 in order to makethe movement of the 'slide certain and accurate. It, therefore, followsfrom the foregoing that by merely pushing forward or toward the left, asseen in Fig. 3, the locking thumb screws 26 until they reach the limitof their forward movement, and then drawing the inner casing downwardly,the magazine may be unlocked and loaded, while the mere pushing of thesaid inner casing 13 upward,will bring the Xparts ofjthe loaded magazineinto operative relationz The pushing of the inner casing home will placethe spring 16 under tension, and thec'artridges will be held inthemagazine bythe turned ,over lips of the outer casing 4, as illustrated,the uppermost cartridge lying inthe path of the bolt 2 ready to beforced forward into the chamber of the barrel. When the last cartridgeis red, the follower rises finto the path of tle `bolt and stopsthemotion of the latter.

The thumb catch 11 preferably extends into the trigger guardfas shown,soV that it may belreadily operated when desired.

IIn tassembling' the parts, the follower is first inserted intothe innercasing 13 and the lugs 20 are inserted in the holes -19 through theslots 14 of the said inner casing.

The advantages of my present invention will be apparent when vit isrememberedthat the usual detachable magazines are mainly 'used in armshaving a solid breech and side ejector. Therefore, the only means ofloading is by detaching said magazines from the arm and `ltting thecartridges into them one at a time. Not only is this a tedious opera-'tion,'but it is liable to'require considerable time at a crisis whensuch time is of thegutmost valuex In my '.device, on the other hand, Vitwill be -seen that the loading is effected without detaching the'magazine at v all. urther, it is well recognized that'the most practicaltype of box magazine is the typeknown as the fixed type, while, on theother hand, the great objection to a detachable magazine asl proved, inactual practice, is the fact that the box being separable from tervalsfor the purpose o imanes the arm is very liable to getll'ost. Now, my

out the disadvantages of the latter. In other words, although the outercasing 4 is not positively fixed to the arm, yet it need not be removedtherefrom except at long in! i cleaning. Also, my ientiremagazine is soconstructed that it canfbe ,taken apart Ventirely by hand without theuse of any tool.

It is obvious that those skilled in 'the art' may vary the details ofconstruction and the arrangement of parts without `departing from thespirit of my linvention, and thereJ fore I do not wish to be limited tothe above disclosure except as may be required by the claims.
